Answer:
I believe the answer would be 21xy + 6x^2
Given

To find the derivative of the give function,we apply below exponent rule first:

So,
Next, we apply the chain rule:
So,
We substitute back u=(5x-6):
Simplify:
Therefore, the answer is:
1Distributive
2Commutative
3Associative
4Commutative
5Associative
